Technical Problem

[4]
The display device has a TFT layer and an encapsulation layer both ends of which are sealed by a sealing member, and a power supply line of a metal material may be provided between the TFT layer and the encapsulation layer. In this state, when an external impact is applied to the display device, cracks may occur in the sealing member provided between the TFT layer and the encapsulation layer, thereby lowering the adhesion of the sealing member and degrading the sealing. Further, moisture may infiltrate into the TFT layer and the encapsulation layer through the cracks, so that the power supply line of a metal material provided between the TFT layer and the encapsulation layer may be corroded.
[5]
Various embodiments provide a display device capable of providing a display panel with high strength by forming at least one insulating layer in the display panel, which prevents cracks from occurring by an external impact, and further provide an electronic device including the same.
[6]
According to various embodiments, first and second insulating layers are formed in the display panel in order to prevent the occurrence of cracks due to an external impact, thereby preventing deterioration of adhesion of a sealing member provided in the display panel. In addition, it is possible to prevent moisture from infiltrating into the lines at least on the basis of the occurrence of cracks in the sealing member of the display panel, and to prevent corrosion or deformation of the lines included in the display panel. In addition to provision of a high strength display panel and prevention of corrosion or deformation of the lines as described above, it is possible to improve the waterproof function of the product, to suppressing an increase in the consumption current of the product, and to prevent degradation of image quality of the display device.

At least one of the elements of the electronic device 300 may be the same as or similar to at least one of the elements of the electronic device 100 in FIG. 1 or 2, and the duplicate description thereof will be omitted hereinafter.
[34]
The first support member 311 may be disposed inside the electronic device 300 so as to be connected to the side bezel structure 310, or may be integrally formed with the side bezel structure 310. The first support member 311 may be made of, for example, a metal material and/or a non-metal material (e.g., polymer).

[40]
According to an embodiment, when the electronic device 300 drops onto the ground, impact may be transmitted to the upper, lower, left, and right edges, as well as the corners. This impact may cause the breakage of the display device 330 to begin from the portion (e.g., the edges of the display device 330) that is most sensitive to impact. However, according to the embodiment, the breakage rate of the display can be significantly lowered, compared to the prior art, by applying a structure capable of remarkably reducing the possibility of breakage even in the case of an impact to the area corresponding to the edges of the display device 300.
[41]
FIG. 4A is a cross-sectional view taken along the line A-A' in FIG. 1, which shows a configuration of a display device according to various embodiments.
[42]
Referring to FIG. 4A, an electronic device (e.g., the electronic device 100 in FIG. 1) may be fixed in such a manner that a display panel 420 is attached to a display mounting surface of a case frame, and a window 410 may be mounted thereon in order to protect the display panel 420.
[43]
The display device 400 may include a window 410, a display panel 420, and a cover panel 430.
[44]
The display panel 420 may include a touch screen panel (TSP) including a touch sensor in an upper area or an inner area of the display panel 420.
[45]
For example, the touch screen panel may be disposed in the upper area of the display panel 420 (e.g., an on-cell type), or may be disposed in the inner area of the display panel 420 (e.g., an in-cell type). Alternatively, a separate touch screen panel may be interposed between the window 410 and the display panel 420.
[46]
According to an embodiment, the display panel 420 may include an On-Cell TouchAMOLED)(OCTA) panel. In the present embodiment, the touch screen panel may be disposed on top of the display panel.
[47]
The display panel 420 may include at least one of an Organic Light-Emitting Diode (OLED) panel or an On-Cell Touch AMOLED(OCTA) panel. Although an Organic Light-Emitting Diode (OLED) panel will be described as an example in the embodiment, the disclosure is not limited thereto. For example, any panel capable of serving as a display of the electronic device can be applied to the display panel 420.
[48]
The cover panel 430 may face the lower surface of the display panel 420 in order to protect the display panel 420.
[49]
The display panel 420 may include a front substrate 421, a rear substrate 422, a sealing member 423, a conductive line 424, a first insulating layer 425, and a second insulating layer 426. The front substrate 421 may be disposed on the lower surface of a touch screen panel (not shown).
[50]
The rear substrate 422 may be disposed under the front substrate 421 so as to provide a space below the front substrate 421. For example, the sealing member 423, the conductive line 424, the first insulating layer 425, or the second insulating layer 426 may be disposed in the space between the front substrate 421 and the rear substrate 422. The rear substrate 422 may be disposed on the upper surface of the cover panel 430.
[51]
The front substrate 421 may include an encapsulation layer, and the rear substrate 422 may include at least one of a TFT layer and a Low-Temperature Polycrystalline Silicon (LTPS) glass.
[52]
An organic material may be disposed between the front substrate 421 and the rear substrate 422 of the display panel 420. A sealing member may be applied via at least a portion of the edges of the display panel 420 such that the organic material is sealed without being exposed to the air. For example, the sealing member 423 may be disposed between the front substrate 421 and the rear substrate 422 so as to seal at least a portion of the front substrate 421, the conductive line 424, and the second insulating layer 426.
[53]
The conductive line 424 may be attached so as to face the sealing member 423 in order to supply power to a plurality of light-emitting devices (not shown) disposed in the touch screen panel and/or at least a portion of the space between the front substrate 421 and the rear substrate 422. For example, the conductive line 424 may include an ELVDD or ELVSS line for controlling the driving of one or more light-emitting devices including one or more sub light-emitting devices (e.g., R, G, or B). The light-emitting device may include pixels.
[54]
The conductive line 424 may be made of a metal material, and the conductive line 424 may include a power supply line or a data signal line. The conductive line 424 will be described as an example of a power supply line or a data signal line, but it is not limited thereto. For example, any line that can be electrically connected may be applied as the conductive line 424. The embodiment will be described by applying a power supply line made of a metal material.
[55]
The first insulating layer 425 may be disposed between the conductive line 424 and the rear substrate 422 so as to protect the conductive line 424.
[56]
The second insulating layer 426 may be disposed between edges of the sealing member 423, the conductive line 424, and the first insulating layer 425 in order to prevent cracks from occurring due to an external impact in the sealing member 423 of the display panel 420 and in order to block moisture infiltrating into the conductive line 424. For example, the second insulating layer 426 may be disposed so as to cover at least a portion of the end of the conductive line 424.
[57]
The first insulating layer 425 or the second insulating layer 426 may include an insulating member. The first insulating layer 425 or the second insulating layer 426 including the insulating member may prevent cracks generated in the display panel 420.
[58]
For example, the second insulating layer 426 may prevent cracks from occurring due to an external impact in the display panel 420, thereby preventing the adhesion of the sealing member 423 provided in the display panel 420 from deteriorating, and may prevent moisture from infiltrating into the display panel 420, thereby preventing corrosion or deformation of the power supply line.
[59]
The front substrate 421 may include an encapsulation layer (e.g., encapsulation glass), or the rear substrate 422 may include at least one of a TFT layer and a Low-Temperature Polycrystalline Silicon (LTPS) glass. For example, the front substrate 421 or the rear substrate 422 may include a glass material. A light-emitting device may be disposed between the front substrate 421 and the rear substrate 422. A sealing member may be attached to the edges of the front substrate 421 or the rear substrate 422 such that the light-emitting device is hermetically enclosed without being exposed to the air. Since the sealing member 114 is generally made of a glass frit composite, a crack may be generated due to an external impact.
[60]
Therefore, at least a part of the outermost portion of the sealing member 423 may be provided with a second insulating layer 426 capable of absorbing an external impact.
[61]
As described above in FIG. 4A, the display device 400 according to various embodiments may include a window 410, a display panel 420 disposed to face the lower surface of the window 410, and a cover panel 430 disposed to face the lower surface of the display panel 420. The display panel 420 may include a front substrate 421 and a rear substrate 422 disposed under the window 410 and a sealing member 423 disposed between the front substrate 421 and the rear substrate 422. A conductive line 424 may be disposed on the lower surface of the sealing member 423, and a first insulating layer 425 may be disposed between the conductive line 424 and the rear substrate 422. A second insulating layer 426 may be disposed between the sealing member 423 and the conductive line 424. The second insulating layer 426 may be disposed at the outermost portion of the sealing member 423 and the conductive line 424, and the second insulating layer 426 may be disposed on the upper surface of the outermost portion of the first insulating layer 425.
[62]
When an external impact is applied to the display device 400 assembled as described above, the second insulating layer 426 may primarily absorb the external impact, and the first insulating layer 425 may secondarily absorb the same. As described above, the first insulating layer 425 or the second insulating layer 426 may absorb an external impact, thereby preventing cracks from occurring in the sealing member 423, and it is possible to prevent moisture from infiltrating into the display device 400 by protecting the conductive line 424. Therefore, it is possible to prevent corrosion or breakage of the conductive line 424 and to prevent deformation of the conductive line 424. According to an embodiment, the first insulating layer 425 or the second insulating layer 426 may prevent cracks from occurring in the sealing member 423, thereby improving the adhesion of the front substrate 421 and the rear substrate 422. Therefore, the strength of the display device 400 can be enhanced.
[63]
According to an embodiment, the first insulating layer 425 or the second insulating layer 426 may prevent moisture from infiltrating into the display device 400, regardless of a crack of the sealing member 423. For example, the first insulating layer 425 or the second insulating layer 426 may prevent moisture from infiltrating into the display device 400, thereby realizing the waterproof function of the display device 400. For example, the first insulating layer 425 or the second insulating layer 426 may be waterproof.
[64]
According to an embodiment, as described in FIG. 4A, the second insulating layer 426 may have an "L" shape. For example, a first surface 426a of the second insulating layer 426 may cover at least a portion of the outer end of the conductive line 424, a second surface 426b of the second insulating layer 426 may face at least a portion of the sealing member 423, and a third surface 426c of the second insulating layer 426 may face at least a portion of the upper surface of the edge of the first insulating layer 425.
[65]
According to an embodiment, FIG. 4B is a cross-sectional view taken along the line A-A' in FIG. 1, which shows another configuration of a display device according to various embodiments.
[66]
Referring to FIG. 4B, a second insulating layer 4261 may have an "I" shape, and the height of the second insulating layer 4261 may be greater than the height of the conductive line 424. For example, the thickness of the second insulating layer 4261 may be greater than the thickness of the conductive line 424. A first surface 4261a of the second insulating layer 4261 may face one surface of the outermost end of the conductive line 424, a second surface 4261b of the second insulating layer 4261 may face at least a portion of the outer end of the sealing member 423, and a third surface 4261c of the second insulating layer 4261 may face at least a portion of the upper surface of the edge of the first insulating layer 425.
[67]
According to an embodiment, FIG. 4C is a cross-sectional view taken along the line A-A' in FIG. 1, which shows another configuration of a display device according to various embodiments.
